Steering Failed Problems of Infiniti Q50

Steering wheel failed to respond. Wheels felt disconnected with the steering wheel. It could have been tragic if I was driving at a higher speed.

Steering failed completely approximately 8/12/15 while on the road. Incident occurred while at a slow pace and I was able to force steer the car to the side of the road. Today I went to start the car in my garage and once again the car had no steering. Dealer was able to fix the problem however I feel that this is a major problem that could be dangerous. For instance, if my wife had been driving in the first incident she would not have strong enough to steer the car to the side of the road. Coast infinity in sarasota, FL 941-924-1211 today the steering failed again but occurred when I started the car in my garage. Was not traveling at the time.

Das steering failed again. This was recalled several times in 2013-2014 for the same problem. Dealer and manufacturer "rectified" problem 3 times. Steerlng seizes up when temperatures fall below 0 degrees. Steering failure and chassis failure come on. Car required towing to dealer each time last year. I was able to get it to the dealer this time, with difficulty, no power steering and steering wheel is 90 degrees off center. Dealer provided a loaner as they had previously. This is still a dangerous problem that Infiniti has not resolved.

The vehicle has direct adaptive steering (das) and has been having failures of the system since cold weather came in early December. At start up the steering error and traction control error lights come on. Most times waiting a few minutes and restarting the vehicle will clear the condition but, not always. When the system is in failure mode the steering is exceedingly stiff and difficult to operate, to the point of making the vehicle unsafe to drive, in my opinion. This failure mode, according to the owner manual, is supposed to be a fail safe mode with reduced steering assistance and direct mechanical linkage to the front wheels. However, the steering effort is substantially higher than with the car turned off, the direct mechanical linkage active and steering the wheels without electrical power applied. I believe there is a serious design defect in either the mechanical aspect of this system or the software that manages it. The steering effort in das failure mode shouldn't exceed the effort required with no electrical power applied to the steering. But, it does, by a very substantial amount. The effort required is of a degree where drivers of low strength would find it difficult if not impossible to adequately control the vehicle. They'd be better off putting the car in neutral and turning off the engine. I consider to this to be a substantial safety concern and in need of investigation. So far, to my knowledge, no one has been involved in an accident or injured from a das steering failure. However, I believe it's a matter of time before someone is either injured or killed from a das failure while the car is in motion because of the way the system behaves when it's in failure mode. The vehicle has been in to the dealer for repairs but, is still exhibiting the problem. It's back in the shop again.

Adaptive steering failed while backing up car and was not able to turn wheel. I stopped the car, restarted the engine and it worked again. The outside temp was 9f, the message indicated a "system malfunction" and referred me to the owner's manual.

The contact owns a 2014 Infiniti Q50. The contact stated that while driving approximately 10 mph, the steering system failed. The contact stated that when he turned the steering wheel to the left it continued to drive straight. The identical failure occurred when the contact shift the vehicle into park. The warning lights also illuminated. The dealer towed the vehicle from a parking lot; however, the failure was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 1079.

Direct adaptive steering system fails at startup along with collision imminent braking system (or maybe vice versa). Failure occurred 2x, but never when the vehicle was cold. Turning off all active safety systems and then restarting the vehicle appears to remedy the problem. Restarting alone was not effective. Vehicle is currently at our local dealership and is having multiple control modules replaced.

The contact owns a 2014 Infiniti Q50. The contact stated that the steering wheel failed several times without warning while driving at highway speeds. The contact had to crash into sand and road gravel to avoid a rear end crash with another vehicle. The contact did not sustain any injuries and a police report was not filed. The vehicle was towed to the dealer where the central computer system was reprogrammed however, the failure was not corrected. The manufacturer was made aware of the failure. The failure and current mileage was 38. The VIN was not available.
